The TOTO Washlet S7 is the new flagship bidet seat from the global industry leading brand TOTO.  Replacing the previous S500e model, the S7 comes with a facelift and a few added features.  Available in an elongated size, the TOTO S7 washlet comes in both Cotton White and Sedona Beige colorways.  

The TOTO Washlet S7 is different from the S7A in that it lacks the automatic opening/closing seat and lid. They are otherwise identical.

The TOTO Washlet S7 comes in 2 lid designs, contemporary and classic.  The contemporary lid design is more rounded and has a seamless look to match most modern toilet bowls. The classic lid has a beveled edge making it more in line with traditional styles.  At just 4.1" in rear height, the TOTO S7 is one of the slimmest bidet seats on the market today. 

A nice update on the Washlet S7 is that TOTO figured out a way to make the seat seamless. This eliminates the gap where dirt has a habit of collecting.

The Washlet S7 can now be used with both regular toilets, as well as TOTO T20/T40 toilets as part of a Washlet+ system. TOTO adjusted the location of the water hose and electrical cord to be able to accommodate both installation types. This also means that it's Auto Flush capable once you pair it with a compatible TOTO auto flush kit (sold separately).

The TOTO S7 also features an updated remote control design. The remote control now utilizes a horizontal layout with larger main buttons. The buttons are all tactile physical buttons instead of the touch capacitive type in the previous generation.  TOTO surprisingly removed the LCD screen on the rear of the remote control. While this saves battery life, it also makes changing advanced settings more difficult.

The TOTO Washlet S7 comes fully loaded with every feature you'd expect in a top of the line bidet seat - and then some. While TOTO washlet’s do not have the strongest sprays on the market, they are very effective and comfortable.

 The S7 uses a tankless water heating system that produces unlimited warm water for the duration of the wash. The dryer is also a strength. The S7 uses Ewater+ to sanitize the nozzle and toilet bowl between uses to keep it extra hygienic.

New Features

New on the S7 is the ability to manually mist the toilet bowl with Ewater+ using a button on the back of the remote. Another new feature is a 'power deodorizer' function that boosts the deodorizer fan into high gear during especially fragrant movements.  

The S7 series will have a lot more fine tuning adjustments available. For example, you can adjust the timing of the auto lid, set a schedule for the power saving modes, set the LED lighting to 'night mode', and more.

Lots of features - too many maybe?

This was easy to install and has all the bells and whistles.
I have shut off quite a few of the many features and just end up using the basics. Perhaps the simpler model would have been a better investment for me.


Heated seat, many adjustments, premisting, nightlight motion activated. Fantastic quality.

Rebecca F.
TOTO Washlet S7

This is a great bidet seat. The premisting function, water pressure, night light, and water temperature functions work well. The remote is not hard to work, although digital display would be nice. It was easy to install, and I like it better than my previous Kohler bidet seat.

Jeremy Lewis
S7 Toto - love it

Little pricey but really like the thin profile. New model has one piece seat for ease of cleaning. I like the lights.
